Rio Celeste

Renting a car for a trip to Arenal is a good idea, and if you tack on a side trip to Rio Celeste, it’s a great idea. This river appears to run the color of blue Gatorade, an optical illusion produced by the scattering of sunlight in the water, which doesn’t allow the blue light to get through. Yeah, it’s complicated. Just go.
